Professional Journey: Can you share your career path and what led you to your current role as Director of Logistics at Enpal?
I started with a classic apprenticeship in logistics at TNT Express, followed by a business degree that I completed alongside my full-time job. The turning point came in Berlin, where I was surrounded by the dynamic energy of eCommerce and start-ups. That environment taught me how to combine process thinking with entrepreneurial speed.
Over time, I developed a leadership approach grounded in stakeholder empathy and continuous improvement. Logistics is both exciting and intense, it touches every part of the business and demands constant cross-functional alignment. One key lesson I’ve learned is to never see a supply chain as “done”, there’s always room to optimise.
At Enpal, I found the ideal environment to bring that mindset into a purpose-driven mission, where logistics is not just a support function but a key growth driver.
Logistics Strategy in Renewable Energy: How does Enpal’s logistics strategy support its mission to make solar energy accessible and affordable for homeowners across Germany?
Enpal’s logistics is built to scale the energy transition. Our goal is to make solar energy affordable, and every element in the supply chain from manufacturing to last-mile delivery directly impacts that goal. The final price of a solar system reflects each logistics step: overseas shipping, warehousing, transport, and installation.
To keep systems affordable, all steps must be efficient, predictable, and fairly priced. That’s why we focus on smart routing (from a warehouse perspective), strong carrier partnerships, and leveraging logistics technology. We don’t see logistics as a cost center, but as a value driver lowering costs, reducing delays, and enabling seamless solar rollouts at scale.
Customer Experience in Logistics: How do you ensure a seamless logistics experience for customers from scheduling to final delivery and installation?
This isn’t easy, many different teams within Enpal are involved. Once a customer is confirmed, the order flows through several interfaces to our warehouse partners. From there, we guide the customer through a transparent post-purchase journey.
We use multiple scan points such as picking, staging, and carrier handover to keep customers informed in real time. Communication is key. We rely on tools like Parcellab to send timely updates and minimise delivery surprises.
Our goal is to proactively manage expectations and give each customer a sense of control and clarity throughout their solar journey. In that sense, logistics becomes part of the customer experience, not just an operational layer.
Integration of Technology: What role does technology play in optimising Enpal’s logistics processes, and are there any recent innovations that have significantly improved efficiency?
Technology is essential. We’ve built a logistics setup that connects our ERP system, warehouses, and carriers to enable informed, data-driven decisions. Every process must be considered end-to-end, with full awareness of its downstream impact.
For example, we use digital tools to determine where a system should be picked and packed, which carrier is best suited, and where the goods are currently located. This all relies on accurate data and well-integrated interfaces.
We’re constantly balancing priorities, warehouse capacity, speed, cost, and customer needs. It’s a daily challenge to allocate resources effectively. Good logistics tech doesn’t just automate processes it empowers smarter decision-making.
Challenges in Logistics Operations: What are some of the key challenges you face in managing logistics for a rapidly growing renewable energy company, and how do you address them?
Speed is both a blessing and a challenge. Enpal moves incredibly fast with new ideas, new products, and new markets emerging all the time. We’ve structured the logistics team to stay agile, with the capacity to handle both short-term fixes and long-term improvements.
One key principle we follow is “antifragility”, we don’t just want to survive volatility; we want to grow from it. At the same time, we support “speedboats”, fast-moving initiatives or new business ideas that demand flexibility and urgency.
Balancing these two worlds takes empathy, clarity, and discipline. We focus on prioritisation, iteration, and honest retrospectives. No logistics setup is ever perfect, but with the right mindset, it gets better with every cycle.
Balancing Central Oversight and Field Execution: How does your logistics strategy balance central control with meeting the on-site needs of local installation teams?
Our team serves two core stakeholders: the end customer and the installation teams. Both need reliable information, clarity, and precise timing. We design tools and workflows that enable communication in both directions, top-down and bottom-up.
This isn’t always easy, given the different systems and priorities involved. But if logistics only thinks from the warehouse outward, we risk overlooking the needs of the teams on-site. That’s why we work closely with operations, project managers, and installers to ensure that deliveries are timely, accessible, and aligned with real-world constraints.
Central control gives us structure but true success comes from how effectively we empower those executing in the field.
Sustainability Reporting: Enpal published its first sustainability report detailing its carbon footprint across the entire value chain. How does the logistics department contribute to these sustainability metrics?
At Enpal, sustainability isn’t a parallel track, it’s embedded in our day-to-day decisions. For every logistics optimisation, we evaluate not just the financial impact but also the effect on our carbon footprint.
A recent example is our new packaging solution for solar modules: by switching to a more compact pallet layout and optimised cardboard structure, we improved load factors, reduced material usage, and lowered transport emissions. It’s a win-win both cost and CO₂ go down.
We also work closely with our waste logistics partner, Junkbusters, to refine pick-up routes and improve recycling rates for leftover materials post-installation. They provide us with detailed reports that allow us to track emissions, diversion rates, and recovery volumes feeding accurate logistics data into Enpal’s broader sustainability reporting.
Ultimately, logistics has a tangible impact across Scope 3 emissions from packaging and transport to end-of-project waste. By being intentional with our setups, we ensure operational excellence and climate responsibility go hand in hand. Sustainability isn’t a side KPI, it’s the lens through which we evaluate every improvement.
Carrier Management and Transport Strategy: How do you approach carrier management and transport optimisation to ensure cost-efficiency and service quality at scale?
We work closely with two logistics partners to manage our carrier network. Our delivery model, B2C site deliveries to private homes under construction, isn’t standard. Not every carrier is willing or able to serve this niche, which is why we carefully select partners who understand the complexity and can still offer competitive rates.
We avoid one-size-fits-all setups. Instead, we strive for antifragility: always improving, never accepting the status quo. We benchmark performance, track KPIs, and align incentives. Carrier partnerships are more than just contracts, they’re collaborations built on shared goals and a common mindset. That makes all the difference.
Reverse Logistics and Site Clean-Up: How do you handle waste and reverse logistics after installation?
Once the system is installed and generating clean energy, our logistics job isn’t over. We need to remove packaging, leftover materials, and recyclable waste from the customer’s property quickly, cleanly, and with minimal disruption. That’s why we’ve built a dedicated “Reverse & Waste Logistics” stream as an integral part of our customer journey.
Our key partner here is Junkbusters. Together, we offer a nationwide on-site waste service that relieves our installation teams from any cleanup responsibility so they can focus purely on delivering quality work. Junkbusters handles customer communication directly, including appointment scheduling, reminders, and confirmations via email and SMS to ensure nothing gets missed.
Logistically, routes are planned for maximum eco-efficiency, and waste is pre-sorted to achieve the highest recycling rates possible. Beyond the physical process, we rely on a market-leading digital waste reporting system. It provides Enpal with real-time insights into every active and completed project, full transparency on recycling rates, CO₂ impact, and operational KPIs.
This isn’t just a post-installation task. It is a continuation of service, environmental responsibility, and a chance to learn and optimise together. For us, holistic logistics means delivering energy and taking everything else responsibly with us when we leave.
Future Outlook: Looking ahead, what are your key priorities for advancing logistics operations at Enpal to support the company’s growth and sustainability objectives?
It may sound simple, but execution is everything. We focus on three main pillars: efficient warehouse processes, high-quality transport through a multi-carrier setup, and proactive communication with customers.
We’re exploring electric last-mile solutions, autonomous vehicles, and robotics but we remain realistic. Infrastructure, regulations, and economics still limit the speed of rollout. In the meantime, we double down on what we can control: clear responsibilities, measurable performance, and strong feedback loops.
Logistics at Enpal is constantly evolving but always with the goal of making our operations more resilient, scalable, and customer-centric.
Advice for Logistics Professionals: What advice would you give to logistics professionals aiming to integrate sustainability into their operations within the renewable energy sector?
Start small but stay consistent. Don’t wait for the perfect strategy to begin. Whether it’s smarter packaging, CO₂ tracking, or switching to greener routes, sustainability needs to become a habit, not a side project.
Collaborate with partners, challenge assumptions, and use data to guide your impact. Most importantly, tie sustainability efforts to real business outcomes. The energy sector offers a unique platform to make logistics a force for good lean into that.
Many small, smart changes will outperform one big initiative. And don’t forget to involve your team, sustainable logistics is a team sport.
